I have read about the 4 sq ft per chicken information a few times. Are the nesting boxes included in the calculation for a coop size? I have 6 growing hens and one rooster. I am hurrying to finish buidling their coop at this moment. They are just over 4 weeks old. I am a few sq. ft (about 5) short if the nesting boxes should not be calculated and will be well within the range if nesting boxes are used to calculate square footage. Am I in trouble?
